1,登录报错如下:

[oracle@oracle_yueworld admin]$ rlwrap sqlplus system/system51@st1

2,查看下lsnrctl状态,看是否是lsnrctl监听的问题

[oracle@oracle_yueworld admin]$ lsnrctl status

The listener supports no services

[oracle@oracle_yueworld admin]$

从中可以看出监听正常,但是The listener supports no services这个貌似是不识别service_name啊

3,去查看下参数

SQL> show parameter name;

NAME                     TYPE    VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert             string  /oracle/app/oracle/oradata/pow
                         erdes, /oracle/app/oracle/orad
                         ata/orcl
db_name                  string  orcl
db_unique_name               string  stunq
global_names                 boolean     FALSE
instance_name                string  orcl
lock_name_space              string
log_file_name_convert            string
service_names                string  stunq
SQL> 

看到db_name和db_unique_name以及service_names不一样


4,解决方案

在listener.ora文件里面添加SID_LIST_LISTENER,如下所示:


[oracle@oracle_yueworld admin]$ more listener.ora 
# listener.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = stunq)
      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = stunq)
    )
  )

LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.51)(PORT = 1521))
  )

ADR_BASE_LISTENER = /oracle/app/oracle

[oracle@oracle_yueworld admin]$ 

再重启lsnrctl服务:

[oracle@oracle_yueworld admin]$ lsnrctl start

The command completed successfully
[oracle@oracle_yueworld admin]$ 

看到The listener supports no services错误已经没有了,可以去试试登录


5,再次登录报错

[oracle@oracle_yueworld admin]$ rlwrap sqlplus  orclk/st141118@st1

SQL*Plus: Release 11.2.0.1.0 Production on Thu Dec 3 18:03:55 2015

Enter user-name: 

6,去修改服务端和客户端的配置文件

google了很多资料,大部分都说是listener.ora配置错误导致listener找不到你要请求的sid。这有两种可能,一种是client端的tnsnames.ora中配置了错误的SID,一种是server端的listener.ora中配置错了SID。仔细检查,然后开始修改服务器listener.ora listener.ora,将SID_NAME修改成正确的instance_name为orcl

[oracle@oracle_yueworld admin]$ more listener.ora 
# listener.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = stunq)
      (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = orcl)
    )
  )
  #PS: 这里面的SID_NAME是oracle实例名,GLOBAL_DBNAME是全局的dbname,是db_unique_name

LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.51)(PORT = 1521))
  )

ADR_BASE_LISTENER = /oracle/app/oracle

[oracle@oracle_yueworld admin]$ 

修改客户端tnsnames.ora

[oracle@oracle_yueworld admin]$ vim tnsnames.ora 

# tnsnames.ora Network Configuration File: /oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

st1 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.121.51)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = stunq)
    )
  )
  # PS:这里的service_name就是可以从执行 show parameter name;中显示的service_names参数值。

7,然后验证登录,成功了,如下所示:

[oracle@oracle_yueworld admin]$ 
[oracle@oracle_yueworld admin]$  rlwrap sqlplus orclk/st141118@st1
